By Mary E. Pearson. Found via Laini Taylor.
This is a book that focuses on a single sci-fi conceit (or maybe one and a half, depending on how you count them) and tells a highly emotional, disturbing story. Honestly, though, I was more disturbed by the ending's moral implications (even in a non-SF world) than by what the technology made possible. This is a book that I will probably keep thinking about for a while (where "a while" is probably the next few days :). Story-wise, it seems pretty tight, although the semi-poetic interludes on the gray pages were a little weird.
Don't read the copyright page Library of Congress summary or find out what book it reminded me of unless you want to be somewhat spoiled.
In the end, I'm somewhat ambivalent about recommending it because of the moral spookiness. There isn't a whole lot of plot: it's all about Jenna's recovery and discovery of herself after an accident her parents won't tell her much about. If you like that kind of very focused story with few characters (and even fewer that matter), then you might like this.
